I search the non-paralle single-thread test of intel. The search results of non-auto-paralle shock me:
SPECfp2006(base/peak)
AMD 1.9GHz - 10.7/11.2
Intel 1.86GHz - 12.3/12.5 (test data: 2007.6.25)
http://www.spec.org/cpu2006/results/...625-01332.html

Intel 3GHz - 18.7/19.3 (test data: 2007.7.23)
http://www.spec.org/cpu2006/results/...723-01537.html

To surprise, the non-paralle result of SPECint2006 is much faster than the paralle result.
SPECint2006(base/peak)
Intel 3GHz 20.2/22.6 (test data: 2007.7.23)
http://www.spec.org/cpu2006/results/...723-01539.html

Which does one rule the single-thread test?
